Serial No. 528,903. i Y m A'fll h erob'ect of this i'venti nis to provide a, strainer of'this kindwith means-by 'whiiclf anj exceedingly large quantity of milk ma'y'fbe' readily and quickly'passed through the'spra iner. y I

j'sti'l l further object of this'invention is to provide fin a d ev'ic'eof this kind means whereby thg straining medium may be readily re- 'lace.""

p The above and various other objects and advantages of'this invention will in part be described in and'in part be understood from the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawing,

1 wherein numeral 10 designates generally a hopper or funnel which is provided at the lower end thereof with an open neck 13 which is adapted to engage the top of a milk can or receptacle.

' 10 In strainers at present in use, the strainers are of a diameter substantially equal to the diameter of the neck portion 13, and where a number of milking machines are used for filling of a single receptacle, the strainer is not of sufiicient capacity to readily pass the milk therethrough as fast as the milking machines are able to draw the milk.

The tapering portion 11 of the hopper 10 is provided with a shoulder 12 at a point above the top of the neck 13, the diameter of the tapering'portion 11 at the shoulder 12- being greater than the diameter" of the neck 13;

' A screen disk or perforated support 14 {is adapted to rest on the shoulder'f12i'and is provided with braces 15 so as "to support the screen andprev ent it' from'jb'ending under the weight 'of'the milk disposed iii the hopper 10.

A filtering'element or strainer {1 is disposta on a l g w 'b hepe e screen thls' telingi 0r i gmniber c mprising a pad composed 'of- 'cotton o1" the like.

An upper perforated plate 17 is disposed on the upper surface of the straininge' lem'ent 16 and is provided at the peripheral'ed es thereof with a depending'fflange l8 -which P engages about the edges of the straining'element 16 and also the supporting perforated disk: or screen 14', Anljupstanding member 19 is mounted on the upper face of the plate p 17 artsubstantially the'center'thereof, and a clamping plate or baflle '2Q'is' adapted toengage'the top of the lug 19 ,'this bafiie 20being adapted to re novably engagelugs 21 carried by the hopper 10; 'This baffle 20 has converging edge portions] which converge from the center thereof toward each end, as indicated at 2 2,and the ends of the baffle 20 are provided with 'arcuate portions 23 for engagement with the interior of the'hopper 10. hen the baflie 20 is in -position,*the F baffle is bowed longitudinally so as to place the bafiie under tension and to resiliently hold the perforated plate 17 into engagement with the straining element 16. In: this manner, the baffle 20 not only preventsthemilk,*-whn poured into the'strainer, from' striking the plate 17. directly so as. to wearzholes or the like through the straining element 16, but this bafiie .alsotensions the strainer softha-t it will stay in position in the event the hop- 1190 per 10 is removed from the top of themilk can. -11

In the use of this device, the straining members 14,16, and 17 may be placed on the shoulder 12 andthebafile 20 extended across the top supporting lug 19 and the ends 23 of the bafliepositioned beneath the lugs'2l mounted on the hopper 10. The milk may be then placed in the hopper 10 during the milking operation, the force of the -milk i striking the bafile 20 and running off therefrom onto the perforated plate 17 through which the milk will pass through the straining elements 16 and 14.

In actual practice, it has been found that by increasing the diameter of the straining elements ,only slightly, the, capacity of the strainer is practically trebled and the straining element 16 through the use of the baflie 20 and the perforated plate 17 will las't a' greater length of timeithan where the straining element 16 is placed loosely on top of the screen 14 or between a pair of perforated" plates. Furthermore, through the use. of the bafile 20, it is possible to' increase the size of the. holesuin the plate 17 inasmuchmsthe baffle20 will-receive the impact ofthemil k so that the stream -or streams. of. milk from the milking machine will not strike thefiltering emb r It is, of course, under stood thatfyarious changes and modifications maybe made, in

the. details of construction and design-of the above specifically described .embodimentof this inYeiltion without departingv from the spi t t e eof, su'ch ch g s nd mQdL fiQe- -tions being restricted only by the scope of t e ol ow g s; v a a I claim;--.
